ABCD Interim Annual Release 1.1

The ABCD Study's Interim Annual Release 1.1 is available to those who have completed the process to gain access to the ABCD Data Repository.

Shared data may change in ongoing updates. The 1.1 Release will be permanently available as a persistent data set defined inNDA Study 576. NDA Study 576 has been assigned the DOI 10.15154/1412097.

Pre-packaged datasets

Release 1.1 is available in two pre-packaged datasets available through the "Shared Packages" view of your Packages dashboard. Each package contains data from the entire Curated Annual Release 1.1, exceptfor the associated images. These will be most useful for users interested in the phenotypic, clinical, and data derived from MRI images. Fast Track data (raw images) are not included in these packages.

One of the packages, titled NDAABCDRELEASE11, will include default NDA variable names for all data elements. This package can be used to create a miNDAR, a cloud-hosted Oracle database as an alternative to downloading it.

The second package, titled DEAPABCDRELEASE11 uses DEAP variable names. DEAP is the Data Exploration and Analysis Platform maintained by the ABCD DAIC and hosted by NDA to support analysis of the data, and this package will be compatible with DEAP, but cannot be used to create a miNDAR database in NDA.

The raw MRI images and the minimally processed imaging files are over 40TB in size which may make data transfer difficult. To access those images, you can use Computational Credits and compute on the data in the cloud without downloading the needed files in their entirety (see here). If you feel that you really need the full imaging data please contact the NDA help desk (NDAHelp@mail.nih.gov) to obtain help in getting the data that you need.

Building a Custom Package

You can also use the query tool to find a subset of the data that are directly relevant to your research questions and download that subset as needed.

All ABCD data, including raw imaging data from fast track updates will be deposited in the ABCD Study Collection 2573. The Shared Data tab lists all data currently available from both Fast Track and Curated Annual Releases.

The following supporting documents are provided for Release 1.1:

Release Notes

Release notes providing supporting information for select data types can be downloaded by researchers who are approved for ABCD data access from the General tab of ABCD Study Collection 2573. They will also be included in downloaded data packages.
